which shall be durable and substantial, at the same time beingserviceable and simple in construction in order to withstand any use, towhich it may be put. I To these endsmy invention comprises a hood whichis preferably rotatably mounted on the discharge end ofthe conveyor, thehood being provided with a hinged. bill or extension which forms acontinuation of the body of the hood and or guide adapted to enlarge orconstrict the discl1argeopening of thehood. Both the apron and bill arecontrolled and adjusted in the discharge a suitable manner, as will hehereinafter set forth.

To all whom it mu, concern: I Be it known that I, ABRAHAM LUKE, acitizen of the United States of America, residin the county of Elkhart'and State of Indiana, have invented certain new and useful Improvementsin. Hoods for cation.

My invention relates to an improvement in hoods for stackers, and moreparticularly to that class of stackers wherein the straw a cornhuskermeans of pneumatic pressure, end of thepipe being provided with a hood gtherefrom to form a suitable novel features of construction andcombinastack. tion of parts, such as will be more fully de- The objectsof my invention are to provide scribed hereinafter, and particularlypointed a'hood of this character which can be so maout in. the claims.

in the accompanying drawings, Figure 1 is a view in side elevation of myimproved hood, showing the bill in its lowered )osition. Fig. 2 is asimilar view showing the ill in its extreme raised position. Fig. 3-is adetail view of the track on which is supported the hood.

My improved hood causes the straw to flow outevenly and continuously and prevents the dropping of straw in bunches,which is a dis l is advantage heretofore encountered.

A still-further object is the provision of a hood capable of rotation,by means of which much as it forms no part of my invention, is

not shown. 7 v

The side edges of the'cut-away portion'of the hoodiorrn'obtuseangles, as shown in the dotted and full lines in Fig.2.-

An apron or guide 7 is hinged at its rear end m to therear edge of thecut-away portion or discharge opening inthe hood, .:.the aproncomprising a plate of a size and shape substantially er uIvalen-t to thearea of the a erture from t e meeting of theinclined ed ges r 5 7 7 'thereof to the reaif 'edge, the plate being I provided with. checks 8 ofgradually-increas mg ,width, extending along the side edges of;

the plate, and adapted to 'overlap'the body portion oft he hood. j Theouter end. of the apron is open and unobstructed,

and a' space. is let t between the outerend of the apron and the loweredge of the curved wall forf dis charging. material under high pressure.

Pivotally secured to the lower end of the curved wall .6 is the billorextension 9, which in sha )e is a continuation of the curved outer endoi the hood and is -provided with the llangeslO 10 to assist in guidingthe straw or other material discharged from the conveyor.

Of-course when it is desired to 4drive thematerial straight out-of the con- 8o veyer the apron is droppeddownand-"the bill raised out of the way, so that while the cheeksconfine the stream against spreading laterally'there is nothing toimpede or break its-force. e 85 Secured exteriorlyofthe cur-veelwall oof the hoodjs a bracket 15', to the upper end of 1 whichis attachedaspr'ing 16, the op osite end of which springis fastened to the bi l,'andthis spring, togethenwith .the force oi'the-ai rressure, normallytendsto raise the bill.
